To rrl uzhmnz't may concern.'

Be it known that I, JOHN J. THACHER, a citizen of the United States ot'America, residing at lVethersfield, in the county of Hartford -ind Stateof Connecticut, have invented new and useful Improvements in ProfilingMachines, of which the following is a specification.

This invention relates to metal Working machines and more specificallyto profiling machines wherein a rotary cutter is c aused in operation tofollow a path conforming to a pattern mounted on the machine and it isthe particular object of the invention to generally improve machines ofthis type.

It is a further object of the invention to generally improve the toollubricating systern of metal cutting machines and to provide improvedmeans for more readily disposing of the chips as they are formed duringthe operation of the machine.

It is a further object of the invention to niount the driving means andcutter-supporting means iii an improved manner and to provide animproved and novel means and arrangement for supporting and adpistingthe cutter supporting saddle on its guide rails.

It is a further object of the invention to improve the accuracy andutility of profiling machines by mounting the former pin blocks in animproved manner whereby the same may be more easily and accuratelyadjusted and firmly secured in adjusted positions.

lVith the above and other objectsin view, which will appear as thedescription pro- (reeds, the invention will now be described bvreference to the drawings wherein:

l Figure 1 is an isometric view of a protiling machine embodying thepresent invention.

Fig. 2 is an end elevation thereof partially broken away to illustratecertain iinproved lubricating features, the cutter-supporting saddlebeing shown in section on the line 2-2 of Fig. 3.

Fig. 'i' is a detail plan view of oneof the cutter heads having theimproved former pin blocks mounted therein. the mounting of one of theseblocks being shown in, horizontal section taken on line 7 7 of Fig. 8.

Fig. 8 is a detail front elevation of the same, showing one ot` theblock mountings in vertical section taken on line 8-8 of Fi. 7.

eferring more specifically to the drawing by reference characters, 1indicates the base of the machine and 2 the supporting column on whichis mounted the arch or saddle supporting member 3 comprising the rails 4and As shown in Fig. 1, I prefer to make the member 3 as a pieceseparate from the base 1 and to secure the said member to the haseabutments 3 by means of bolts 3. lt should be noted that theseabutmciits are entirely within a large chip and oil basin to behereinafter described. The saddle G is mounted to slide along the railsand vertically slidablymounted thereiii are the cutter heads 7 whichsupport the cuttcrspindlcs 8 and the usual former pins. As is usual inthis type of machine, the saddle may be moved along the rails by meansof a rack and pinion mechanism 9 and an operating handle 10. The Work isadapted to he supported on the table 11 which may be moved on the Ways12 in a direction at right angles to the movement ot' the saddle bymeans of a handle 12. I provide the table with the usual trough 1l andfurthermore prefer to provide an overhanging lip 11 leading from thetrough whereby the table guideways are kept tree from chips and cuttinglubricant.

As heretofore stated, one object of my invention is to provide improvedmeans to care for the oil or lubricating compound and chips coming fromthe work fable and in this connection it should be understood thatthroughout the specification the term oil is used in a broad sense toindicate a lubricant or lubricating or cutting compound.

This improved construction is shown in Figs. 1, 2, 4, 5 and 6 wherein Ihave illustrated a large chip and oil basin 13 preferably inte ral withthe column 2 and entirely surrounding the work table and its supportingguides. As before stated, the rail member 3 is entirely supported withinthis basin on abutments 3. Also the rails and cutter operating partsmounted on the rails are directly over the basin whereby any oildripping from such parts or down the rail supports falls directly intothe basin. The base of the machine preferably rojects forward as at 14wherein is provi ed an oil reservoir 15 with one or more ports leadingthereinto. I preferably provide two such ports and mount a removablechip screen 16 within each and directly above each of the screens. asshown in Figs. 1 and 2, I support a removable chip pan 17. suchconstruction permitting quick and easy removal of the chips and easyaccess to the reservoir for cleaning or other purposes. It should benoted that the screen 16 prevents any chips from dropping into thereservoir 15 Where the pan 17 is removed. The chip and oil basin 13preferably extends to the front and rear as shown in Fig. 2- in suchmanner as to project entirely over the base of the niachine and beneaththe work tabl(J and the inner surface of such basin at all points slantstoward the channels 18 leading respectively into the removable chippans. It should be clear that the novel features herein disclosed may beembodied in machines of designs other than the one shown herein. one ofthe foremost features of the invention being the large chi and oil basinsupported beneath and exten ing outside of the operating table and aremovable oil-draining chip pan so located relative to the basin that itmay readily be removed to dump the chips therefrom. During the operationof the machine,` the chips as well as the lubricant are caught by thebasin 13 as they fall from the table 1l, the arrangement preferablybeing such that the basin performs this function in all positions of thetable. It will also be noted that the basin extends beneath all theoperating parts of the machine in such manner that any oil dripping fromsuch parts falls into the basin where it is carried to the reservoir 15.I also prefer to provide bafile-plates 19 and 19 at each side of themachine lwhereby any oil dripping from tue outer portion of the rail isdeilected into the basin. It will be clear that the shape ofthe basin 13is such that the chips and lubricant are Washed from the higher levels12% to thc lower levers 13" and down the channels 18 into the removablepans 17 where the lubricant is drained off leaving the chips in the ans.The chips may be easily removed by ifting the pans through the space oropening beneath the channels 18 at the front of the machine and dumpingthe chips therefrom. The lubricant is used over again by being pumpedfrom the reservoir by a pump 20 and connections shown in Figs. 1 and 2.

In profiling machines of the present type, it. is essential that alloperating parts be as rigid and free from looseness and lost motion aspossible. lVith such end in view, I provide a novel means andarrangement for supporting and adjusting the saddle on the supportingrails in an improved manner. This means comprises a taper gib 21 whichpreferably is of a length to span the entire length of the saddle 6. Asshown in Figs. 1

and 2. I form a preferably integral elongated projection 22 on thesaddle, such projection being adapted to cooperate with the upperrail-engaging portion 23 in supporting the saddle. I mount the gib 21between this projection and the upper surface of the lower rail and Iprovide means, preferably a screw 24 as shown, for adjusting the giblongitudinally to take up any wear or looseness of the saddle on therail. It will of course be understood that the lower surface of theprojection 22 is tapered or inclined to conform to the taper of the gib.By supporting the major portion of the saddle on one rail und byperforming all the adjusting operations on a single rail by means of asingle elongated gib, the mounting of the saddle is rendered strongerand more accurate than on like machines heretofore used.

As a further means for preventing vibration and rendering the machinemore accurate, I prefer to mount the driving drum directly on the bodyof the machine rather than on the rail member 3 as has been the usualpractice heretofore. As shown in Fig. l, I secure the brackets 25directly to the machine body' at 25' by means of suitable bolts. Thedriving drum 26 is rotatably supported in these brackets and through thebelts shown drives the cutter spindles. As has been heretofore stated,the cutter-supporting member 3, as Well as the table 11, is also mounteddirectly on the machine body. It will be seen that by this construction,all the main movable parts of the machine are mounted separately on thebody whereby the vibratory effect of one on the other is reduced to aminimum, such feature being of particular importance in a. machine ofthe type illustrated.

As a further means of improving the construction of the present machine,I provide a novel form of mounting for the former pin blocks, suchmounting being shown in all the views of the. drawing as a part of thepresent machine. As is usual in this type of machine I provide a formerpin mounting on both sides of each cutting tool` such pins serving tooperate on a right or leftl hand pattern respectively. Referringparticular` 1,4ee,e 1 i 1y to Figs. 7 and 8 wherein I have illustratedthe former pin construction in detail, S illustrates the tool spindlemounted in the vertically slidable tool head 7. Eachside of the head 7is recessed as at 27 within which I preferably mount the-former pinblock 28, each block having a former pin as 29 secured therein b meansof the clamping bolts 30. Each b ock is preferably recessed laterally asat '31, such recess being adapted to receivev therein means, such as apin or bolt 32, whereby the bloclg is prevented from vertical movementwithin the recess 27 but may be readily removed when desired. l

I secure the block in the recess 27 by a clamping means including aclamping screw threaded into the head 7, the arrangement of the clampingmeans being such that the block is crowded or wedged into the ,recess ina manner to fully prevent any lateral movement thereof. his clampingmeans preferably comprises a curved clamping head* 33 mounted on thebolt 34, such head being adapted to engage the block adjacent one cornerthereof and to force the blocksecurely into the opposite corner of therecess. As shown in Fig. 7, I also preferably chamfer off the block asat 35 and the adjacent corner of the head as at 36 whereby to form arecess to receive the clampin/ghead 33 in a' we'dging position therein"As a means for adjusting the block laterally relative to the toolspindle 8, I prefer herein to provide a taper gib or wedge, as 37, theside of the block adjacent to the gib being likewise inclined or taperedto fit the gib. I also prefer to provide a positive means for adjustingthe gib longitudinally and as sucha means for this purpose I hereinillustrate a screw 38 threaded into the block and having a positiveengagement with the gib, as by means of a flange 39 engaging a notch 40in the This construction provides a positive and accurate means foradjusting the gib in both directions longitudinally. After the block isadjusted to the desired position, the clamping bolt 34 is tightened andthe block thereby forced tightly into the opposite corner of the recessand against the gib 37. As will be observed. this novel block mountingconstruction provides for a very line and accurate adjustment of theblock laterally in the recess, prevents the block from any verticalmovement. and provides a means whereby the block may be securely clampedagainst any lateral movement in the bead 7.

From the above description taken in connection with the drawing it isthought that the general operation of the improved machine and theadvantages of the present improvements thereon will be readilyunderstood. However while I have illustrated the invention as beingcarried out by certain mechanism shown in the drawing, it should beclearly understood that the invention is not limited to such structureshownbut may be varied within the scope of the appended claims.
